Description of problem:

When I press the Volume +, Volume - or Mute keys on my Microsoft
internet keyboard, which I have bound to Volume Up, Volume Down and
Volume Mute, respectively, under Keyboard Shortcuts, the box that pops
up to show the current volume settings always appears in the
upper-left of the screen for the first keypress.  If I hit one of
these keys quickly before the box disappears, it moves to the correct
position in the center of the screen and stays there for all
subsequent key presses.  If I wait for the box to disappear before
hitting the key instead, it will appear in the upper-left once again.

Version-Release number of selected component (if applicable):

control-center-2.7.1-3

How reproducible:

Always.

Steps to Reproduce:
1. Bind the volume keys on a multimedia keyboard to change volume
settings.
2. Press one of the keys once.
  
Actual results:

Volume settings box will appear in the upper-left of the screen.

Expected results:

Volume settings box should appear in the center of the screen.
